The UFC announced on Tuesday that both UFC featherweight champion Jose Aldo and Quinton "Rampage" Jackson have been forced off the October card from Brazil. No replacement opponents for either Frankie Edgar or Glover Teixeira have been announced by the promotion, or any new fights to replace the previously scheduled ones.

Of course, it's also possible that this has nothing to do with the October card and that Machida will be making another announcement of some kind.

Silva added some fuel to the fire, posting a message on Twitter that read, "UFC RIO???" Silva has talked about competing once more this year after falling to Rich Franklin earlier this year in Brazil.
